In this Article, the legend of Figure 5 and Figure 6 are incorrect:

In Figure 5:

"Phylogenetic analysis of RPSA in insect species.

Neighbor-joining method was used to construct the phylogenetic tree. Bootstrap values with 1000 trials are indicated on branches."

should read:

"Quantification of the expression level of fruitless gene in ovary and testis of P. americana with real-time PCR.

The expression level of this gene in ovary was set as 1. All the data collected from the real-time PCR analyses were shown as averages ± SE; P < 0.01"

In Figure 6:

"Quantification of the expression level of fruitless gene with real-time PCR.

The expression level of this gene in female P. americana was set as 1. All the data collected from the real-time PCR analyses were shown as averages ± SE; P < 0.01."

should read:

"Quantification of the expression level of RPSA gene with real-time PCR.

The expression level of this gene in female P. americana was set as 1. All the data collected from the real-time PCR analyses were shown as averages ± SE; P < 0.01."
